a) In an inductor voltage leads current by \frac{\pi }{2} and in resistor both voltage and current are in the same phase, the resultant of e_{L} AND e_{R} that is e in the diagram will lead by phase \phi . So the resultant current will also lead by a phase \phi

(b) Given;-

       current\; i=1.0\; A

\because V_{R}=160\; V\; \; \; \; \because V_{L}=120\; V

R=\frac{V_{R}}{I}=\frac{160}{1}=160\Omega\; \; \; \; \; \; X_{L}=\frac{V_{L}}{I}=\frac{120}{1}=120\Omega

V_{net}=\sqrt{V^{2}_{R}+V^{2}_{L}}=\sqrt{(160)^{2}+(120)^{2}}=\sqrt{25600+1440}

V_{net}=200

Now, calculating the impedance (Z) of the circuit.

Z=\sqrt{R^{2}+X_{L}^{2}}=\sqrt{(160)^{2}+(120)^{2}}=200\Omega

(c) When direct current is passed through the circuit the potential difference across the inductor is zero.

The potential difference of the circuit = potential difference across the resistor
